Security locked the doors

[GoodTaste]

When Marion Koopmans, a virologist at Erasmus University Medical Center, visited a museum in Amsterdam with her family last year, she was spotted by the wrong crowd: people who hate Koopmans because of her work on COVID-19. “They started really yelling, banging,” she says. “Security locked the doors.”

Does Security locked the doors sound natural? I believe The guard(s) locked the doors is more natural.
